Reverb effect

A reverb effect, or reverb, is an audio effect applied to simulate reverberation. It may be created through physical means, such as echo chambers, or electronically through audio signal processing. The American producer Bill Putnam is credited for the first artistic use of artificial reverb in music, on the 1947 song "Peg o' My Heart" by the Harmonicats.

Spring reverb, created with a series of mounted springs, is popular in surf music and dub reggae. Plate reverb uses electromechanical transducers to create vibrations in large plates of sheet metal. Convolution reverb uses impulse responses to record the reverberation of physical spaces and recreate them digitally. Gated reverb became a staple of 1980s pop music, used by drummers including Phil Collins. Shimmer reverb, which alters the pitch of the reverberated sound, is often used in ambient music.
